The importance of the Cho-Maison monopole follows from the following facts. First, as the electroweak generalization of the Dirac monopole, it must exist if the Standard Model is correct [1]}, [2]}. Moreover, the prediction of the mass strongly indicates that it could actually be produced at LHC in the near future. So, when discovered, it will become the first magnetically charged topological elementary particle in the history of physics. Second, it could have deep implications in cosmology. This is because it could induce the density perturbation in the early universe and generate primordial magnetic black holes which could explain the dark matter. As importantly, it could become the seed of the large scale structures of the universe and become the source of the intergalactic magnetic field [3]}. For these reasons MoEDAL and ATLAS at LHC are actively searching for the monopole [4]}, [5]}.
